Application filed June 8, 1926, Serial No. 114,450, and in Germany March 4; 1926.

Our present invention has for its object to provide an improved heat insulatingbottle,

which has many advantages bottles heretofore used.

over insulating In the bottle according to our invention the glass is madethick where the bottle is submitted to a maximum strain,- whereas in known insulating bottles the contrary will be found, whereby many bottles will be broken already in the assembling operation.

Our improved insulating trated by way of example in bottle is illusthe accompany ing drawing, an elevation partly in section of the bottle.

The bottle has a reinforcing portion a sery'' ing to resist to the threaded ring 6. -Sa 1d ring is provided with screw-threads and W111 be engaged upon the bottle from below, so

that said ring will be tightened upon the reinforced portion a of the bottle. 1 Now as the ring 6 owing to the abrupt'reinforcing of the glass of the bottle'has a larger periphery than the glass itself, it will occur that owingto the threaded 0 ap 0, which will be threaded onto the ring 7), the glass bottle willbe freely suspended within the sheetiron casing (Z. Upon tightening the threaded cap 0, the ring I) will be firmly tightened upon the reinforced portion Now the whole will be screw tecting casing cl and thus, owing to the large clearance between the glass tecting casing, which is the same at the bot-.

a of the bottle. ed into the probottle and protom, the glass bottle will be safe not only when assembling the parts, shocks are produced. of this kind the insulated cork. Now if a pressure is but also when In most structures bottles rest on produced upon the bottle from the top thereof, as will be the case by inserting the stopper into the same, the cork arranged on the bottom of the protecting casing will yield in most cases with the result'that the discharge nipple f willbe broken ofl'. The de more provided with :1 pr screwed onto the cape,

Vice is furtherotecting, cap 0 o In our improved device the bottle may be it easily and conveniently cleaned owing. to thesimplicity of construction the'reofj Having now fully described our saidinvention what we claim andJdes1re tosecure by Letters Patent, is:

1. In an insulating bottle, aglass bottle having the upper portion thereof thickened reinforce from the bottom of the bottle, y

and a casing cooperatingwith the ring "and binding the-same upon the reinforce.

2. In-an insulating bottle, a glassbottle having'the upper portion thereof thickened 1 p to present an outstanding reinforce, a ring cooperating with the reinforce and having an internal diameter slightly less'jthan the maximum external diameter of .the reini force, whereby the ring can only engage with the reinforce from the bottom of the bott-le, v

and a casing cooperating with the ring and bindlng the same upon the reinforce, said casing being spaced fromthe bottle 'throughout the full length of the latter-below the ring. 3. In an insulating bottle, a glass bottle having the'upper portion thereof thickened to present an outstanding reinforce, a ring cooperating with the reinforce and having an internal diameter slightly less than the maximum external diameter of the reinforce, whereby the ring can only engage with the reinforce from the bottom of the bottle, a

cap carrying section having threadediconnection-with the 'ring,- and a casing'having threaded connect-ion Wlt-ll'llh cap'carrying section and enclosingthatportion of the bottle below the ring. 1

In testimony whereof we have hereunto set our hands. s s 1 ALBERT GUNTH R H RD GERTLOFF.
